SCREW-EYE-AFFIKING MACHINE.

T0 all whom t may concern.' I

Be it kno-wn that I., WALTER H. RUDOLPH, a citizen of the United States, and a resident of `West Hartford, in the county of Hartford and the State of Connecticut, have invented a new and Improved Screw-Eye-Aflixing Machine, of which the following is a speci- -fication My invention relates more especially to l0 that class of machines for aiiiXing screweyes as in the ends of handles for brushes, brooms, and the like,` and an object of my invention, among others, is to provide a machine of this class that shall be simple in its construction, effective in its operation, and one by means of which` the screw-eyes may be rapidly secured .in place.

One form of machine embodying my involition, and in the construction and use of whichthe objects herein set out, as well as others, may be attained is illustrated in the accompanying drawings, in which- Figure 1 is a plan view of my improved machine with parts broken away to show construction and illustrating their relative position at the beginning of the operation in aixing a screw-eye.

Figure 2 is a view in side elevation of my improved machine. Figure 3 is an end view.

Figure 4 is a detail view illustrating the position of the parts at the end of the operation of afiiXing a screw-eye.

Figure 5 is a detail view, scale enlarged, looking at the end of the spindle.

F-igure 6 is a side view of the spindle, same scale, partly broken away in lengthwise central section. Y

In the accompanying drawings the numeral 7 denotes a. bracket suitably formed for attachment to a table, bench, or the like and having bearings 8 9, rising therefrom to support a spindle 10, that may be driven as by means of a belt from any suitable source of power engaged with pulleys 11-12, one of which is secured to the spindle and the other of which is a loose pulley.

A head 13 is secured to the bearing 9 in any suitable manner, the spindle 10 passing through the bearing 9 and through said head. This spindle has a screw-eye receiving recess 14, spherically formed as and with a screw-eye receiving slot 15 in the bottom of said recess. Pins 16 extend through holes made diagonally through the end o-f porting the spindle 10, as illustrated in Fig. 6 of the drawings, the ends of these pins being located on opposite sides of the slot 15, aswell as upon opposite sides of the recess 14, and as illustrated in Fig. 5 of the drawings, said pin ends being thus located to engage with opposite sides and opposite edges of a screweye when it is inserted within the said recess.

A plunger head 17 is mounted upon suppins 18 secured toy and projecting from the face of the head 13, springs 19, seated with one end of each spring in a recess 20 in the face of the head 13, thrusting against the plunger head and forcing it outwardly away from the head 13. This plunger head has a handle receiving recess 21 in its .outer face from which an opening 22. eX-

tends to the rear face of the head, and stops 23, in the form of screws adjustably secured in the plunger head, are employed to limit its movement toward the head 13, said screws preferably passing through the plunger head and being provided with lock nut-s 24 to retain them in position.

1n the operation of the device a screweye 25 is started in the end lof a handle 26 `just sufficiently to retain the eye in place until it may be inserted in the machine. The end of the handle with the screw-eye thus located therein is seated in the boti tom of the recess 21 with the eye projecting through the opening 22 into the mouth of the recess 14. The handle is pressed inwardly thereby forcing the plunger head 17 toward the head; 13 and consequently seating the screw-eye 25 within the slot 15 and between the pins 16. The spindle, which is rapidly rotating at this time, will thus cause a rapid rotation of the eye, and the handle .26 being held manually against rotation, the eye is quickly screwed into the handle to its full extent. The pressure of the handle against the plunger head 17 moves said head toward the head 13 until the stops 23 arrest such movement, and this will take place at about the time that the screw-eye is nearly screwed into the end of the handle 26. Thereafter the action of the thread on the screw-eye as it is rotated will screw it further into the handle and thereby withdraw said eye from the slot 15 and from between the pins 16, thus permitting the spindle 10 to rotate independently of the screw-eye after the latter has been screwed to place. In accordloo ance With the provisions of the 'patent' statutes I have described the principles of operation of my invention, together with the ldevice which I now consider to represent a rotatably mounted spindle having in its end means toi, engage opposite sides of a screw-eye to rotate it, and a plunger head mounted for reciprocating movement toward and from the spindle, said head being located for free access to receive a portion of a manually supported device With a screw-eye therein and said head having a cavity at its outer side for self-centering the device therein.

2. A screw-eye aiiixing machine. includ ing a rotatably mounted spindle, means on said spindle to receive a screiveye to ron tate it, a plunger head located for free access to receive a portion of a manually sup* ported device with a screw-eye therein, said head having an opening therein enlarged at its outer end for self-centering the device, and means for preventing rotation of said head.

3. A screw-eye aflixing machine including a `rotatably mounted spindle'having its end formedV to receive a screvv-eye, andaplunger vhead mounted for reciprocating movement toward and from theend yof the spindle and located for free and unobstructed access to receive a portion of a device manually engagedV therewith, said head having an opening through which the screw-eye is passed to engage the end of the spindle and being constructed at its outer side for selfcentering the device. c

4. A screWeye afIiXing machine including a bearing, a spindle rotatably mounted in said bearing and with ,its end projecting therefrom for free and unobstructed access thereto, said spindle having its end formed to receive a screw-eye, a plunger head mountedv for reciprocating` movement toward and from the spindle, the axis of said spindle and head being horizontally disposed and said head being formed at its outer side to receive and self-center the end of a device manually engaged therewith land having a screw-eye therein to engage the end of the spindle, and means for 'limiting movement of the plunger head toward the end of the spindle to effect disengagement lof the screw-eye With the spindle by rea son of the threaded engagement with and movement of said eye into said device.
